IMO, there is a big difference between JSP and BXML. BXML is a shortcut for instantiating class hierarchies. You can optionally script it, but it is nowhere near as unstructured as JSP, which let you inject script or other content pretty much anywhere. It is much closer conceptually to the markup languages used by Flex and Silverlight (MXML and XAML, respectively). Your point about debugging is valid, but it only applies if you are using script code. If your BXML file is backed by a class that implements Bindable, you can wire up your event listeners in Java and step through it like any other Java code.
